damage.
level may even lead to a serious consequence according to conditions. Both instruction levels must be followed
because these are important to personal safety.
 Electric Shock Prevention
Warning
 While the inverter power is ON, do not open the front cover or the wiring cover. Do not run the inverter with the front cover or the wiring cover removed. Otherwise
you may access the exposed high voltage terminals or the charging part of the circuitry and get an electric shock.
 Do not remove the inverter front cover even if the power supply is disconnected. The only exception for this would be when performing wiring and periodic
inspection. You may accidentally touch the charged inverter circuits and get an electric shock.
 Before wiring or inspection, LED indication of the inverter unit operation panel must be switched OFF. Any person who is involved in wiring or inspection shall wait
for at least 10 minutes after the power supply has been switched OFF and check that there is no residual voltage using a tester or the like. For some time after the
power-OFF, a high voltage remains in the smoothing capacitor, and it is dangerous.
 Any person who is involved in wiring or inspection of this equipment shall be fully competent to do the work.
 The plug-in option must be installed before wiring. Otherwise you may get an electric shock or be injured.
 Do not touch the plug-in option or handle the cables with wet hands. Otherwise you may get an electric shock.
 Do not subject the cables to scratches, excessive stress, heavy loads or pinching. Otherwise you may get an electric shock.
 Injury Prevention
Caution




The voltage applied to each terminal must be the ones specified in the Instruction Manual. Otherwise a burst, damage, etc. may occur.
The cables must be connected to the correct terminals. Otherwise a burst, damage, etc. may occur.
The polarity (+ and -) must be correct. Otherwise a burst or damage may occur.
While power is ON or for some time after power OFF, do not touch the inverter as it will be extremely hot. Touching these devices may cause a burn.

If halogen-based materials (fluorine, chlorine, bromine, iodine, etc.) infiltrate into a Mitsubishi product, the product will be damaged. Halogen-based materials are
often included in fumigant, which is used to sterilize or disinfest wooden packages. When packaging, prevent residual fumigant components from being infiltrated
into Mitsubishi products, or use an alternative sterilization or disinfection method (heat disinfection, etc.) for packaging. Sterilization of disinfection of wooden
package should also be performed before packaging the product.
Trial run
 Before starting operation, each parameter must be confirmed and adjusted. A failure to do so may cause some machines to make unexpected motions.
Warning
Usage
 Do not modify the equipment.
 Do not perform parts removal which is not instructed in this manual. Doing so may lead to fault or damage of the product.
Caution
Usage
 When parameter clear or all parameter clear is performed, the required parameters must be set again before starting operations. Because all parameters return to
their initial values.
 Static electricity in your body must be discharged before you touch the product.
Maintenance, inspection and parts replacement
 Do not carry out a megger (insulation resistance) test.
Disposal
 The inverter must be treated as industrial waste.
General instruction

ENCODER FEEDBACK CONTROL
Mount FR-A8AP to an FR-A800 series inverter to perform encoder feedback control under V/F control or Advanced magnetic
flux vector control.
This controls the inverter output frequency so that the motor speed is constant to the load variation by detecting the motor
speed with the speed detector (encoder) to feed back to the inverter.
For the details of the parameters used for encoder feedback control, refer to the Instruction Manual (Detailed) of the inverter.
